To all whom it may concern:

Be it known that T, SrENoER G. CARY, a citizen of the United States,residing at the city of New York, borough of Brooklyn, county of Kings,and State of New York, have invented a certain new and useful Means forJoining Metal Package-Binders,

of which the following is a specification.

This invention is a means for joining the meeting end portions of ametal binder after it shall have been positioned around a shippingpackage of one form or another.

The invention is useful, more particularly, in connection with a flatmetal band or strap, and, furtheryas a means for securely retaining thelapping portions of such strap in immovable or fixed relation to eachother, whereby tension placed upon the strap in the operation ofstretching the latter around a shipping package will not pull thecoupling or splice apart. V

In the art of binding or strapping shipping packages, it is usual tosupply the band or strap from a bundle or coil and to use straps inlengths which vary according to the external dimensions of the package,hence in nearly all instances it is not feasible to employ bands orstraps, the end portions of which are specially constructed with a viewto facilitating the operation of joining the meeting ends.

Manifestly, a means for joining or splicing the meeting end portions ofa band or strap must be simple, strong, durable, and eficient, andmoreover, capable of easy and quick manipulation.

According to my invention, a splice plate is used as the member forreceiving the straight end portions of a binder, usually a band orstrap, said splice plate being provided with one or more loops which,when subjected to pressure, deflect the lapped portions of the binder soas to produce shoulders therein, whereby the splice plate and theshouldered portions of the binder are so locked-together that the binderends are held against pulling apart by the tension placed upon saidbinder or by rough usage to which the shipping package may be subjectedduring transportation. 7

Other features and advantages of the invention will? appear from thefollowing detailed description taken in connection with the drawings,wherein Figure 1 is a plan view of a portion of a Specification ofLetters Patent.

binder with the splice plate fitted to the lapped end portions thereofprior to compressing the binder and splice plate into locking relation.

Fig. 2 is a longitudinal section, and Fig. 3 a cross section, throughthe parts in the condition of F ig..1.

Fig. t is a longitudinal section and Fig. 5

a cross section through the splice after the parts shall have beensubjectedto pressure in order to effect the interlocking engagementbetween the splice plate and the binder end portions.

Fig. 6 is a plan view illustrating another embodiment of the spliceplate, wherein, a single loop is employed instead of the double loopshown in the construction of Figs.

.condition so that they may be readily passed through or inserted into asplice member, two forms of which are shown in the drawings.

j The spllce member B shown in Figs. 1 to v5 inclusive, consists of asubstantially flat plate 6 and a plurality of loops 0. The plate and itsloops constitute a single stamping, the plate being cut from a piece ofmetal and the loops being stamped or struck up from the body of theplate, whereby the loops are off-set from the plane of the plate. Theoperation of stamping or striking up the loops from the body of theplate produces a plurality of slots in said plate, the loops beingopposite to the slots, and the end portions of the loops being mergedinto the plate, see Fig. 3. It is apparent that the operation of cuttingthe plate and stamping said plate to produce the slots and-the loops,can be performed rapidly by's'uitable machinery, so as to economicallymanufacture the band ends to a desired position, but in order to jointhe band ends against pulling apart under the tension on the band, it isnecessary in this invention that pressure be applied to the splicemember and the band ends, in order to effect an interlocking engagementbetween the overlapping band ends and the splice member.

When pressure is applied'laterally to the splice member and the bandends, the metal is displaced to effect the interlocking engagement in amanner illustrated in Figs. 4 and 5. According to this invention, theapplication of pressure displaces the loops 0, 0', so as to 'flattenthem with'respect to the plane of the plate, and such displacement ofthe loops forces the metal of the overlapping band ends more or lessinto the slots d of the splice member, as a result ofwhich shoulders care produced at a number of points in the length of the overlapping bandends, which shoulders e have interlocking engagement with the plate at amargin of the slots therein, and said shoulders have interlockingengagement also, with the loops at the margins thereof, see Fig. 4E. Thelapped band ends are thus crimped simul-' taneously into lockingengagement with the plate, and the loops thereof, and such interlockingengagement is obtained at a number of points in the length ofeach endportion of the band, as a result of which the band is so locked with thesplice member that the end portions of the band cannot be pulled apartby tension applied to the band. It is to be understood that the band ispositioned upon a shipping package, such as acase, crate, etc., and saidband is stretched around the package, preferably by pulling upon therespective end portions of the band, the efl'ect of which is to applythe band under tension tothe shipping package and to position therespective end portions 01, a of the band into overlappmg relation.'While the band is under tension, the splice member is slipped overthe'meetingend portions until it reaches a desired position, and thenpressure is applied, through thezinstrumentality of a suitable tool, soas to compress the loops and displace the metal of the overlapping bandends, whereby the parts are locked securelyto ether.

The operations of assembling the splice member and compressing saidsplice member or its loops, are very easily and quickly performed, forthe reason that the end portions of the hand are in a straightcondition, and the loops of the splice member are open for the freeintroduction of the i band ends, thus enabling the operator to easilyand quickly position the splice member upon the band ends, after which atool is positioned upon the splice member, and said tool is operated tocrimp the band ends and simultaneously therewith lock the splice memberto the band ends.

The splice shown in Fig. 6 of the drawings' involves substantially thesame construction of the splice member and the crimping of theband endsthereof, as heretofore described. As shown the splice member B isprovided with a single loop 0', the latter being struck up from theplane of the splice plate so as to produce a slot (1, there being asingle loop and a single slot in the splice member B. The end portionsof the band are inserted into the loop of the splice member B, and thelatter is shifted to a desired position with respect to said lapping endportions, after whlch pressure is applied so as to compress the loop band to crimp the lapping end portions into locking engagement with thesplice member and its loop.

Havm thus fully described the invention, what I c aim as new and desireto secure by Letters Patent is:

1. A splice of the kind described embodying a substantially fiat splicemember provided with one or more bridge members, and a binder the endportions of which are in. lapping relation and are positionedintermediate the substantially flat portion of said splice member andthe bridge members thereof, said bridge members and the lapping portionsof the binder being compressed into substantially the plane of thesplice member and said lapping portions of the binder being interlockedwith each other and with the splice member, and said splice member beingprovided with means for permitting said lateral compression of thebridge members and the binder end portions for positioning the samesubstantially in the plane of said splice member.

2. A splice of the kind described embodying a substantially fiat slottedplateprovided with one or more loop-shaped bridge members, the latterbeing normally positioned in spaced relation to said plate, and a hinderthe end portions of which are in lapping relation and are adapted forfree insertion within said loop shaped bridge members, said lappingportions of the binder and. the bridge members being displaced bypressure-into substantially the plane of said plate and said-lappedbinder portions being interlocked with each other and with the spliceplate.

3. A splice of the kind described embodying a substantially-flat plateprovided with a slotand a loop-shaped bridge member which spans saidslot and is ofl'set from the plane 0 said plate, and a binder thelapping endportlons of which are positioned intermediate the bridgemember and said member to bring said lapped portions and said bridgemember into substantially the same plane as the plate, said crimpedlappedportions of the binder having locking relation to the plate andthe bridge member.

5. A splice of the class described embodying a substantially flatslotted plate provided with one or more bridge members positioned tospan said slot and offset from the plane of the plate, and a binder withlapping' end portions positioned intermediate the plate and said bridgemembers, said bridge members and the lapping binder portions beingdisplaced to lie in substantially the same plane as the plate and saidlapping binder portions being crimped within the slots of the plate soas to produce shoulders which are in looking engagement with the plateand the bridge members.

6. A splice for metal package binders embodying a member provided with aloop struck up from the body of the member and producing therein a slotand forming a space for the free introduction of the end portions of thebinder so as to position said end portions into lapping relation, saidloop being displaceable by the application of lateral pressure forcrimping the lap ed portions into the slot of the splice mem er,

and for efiecting an interlocking engagement between the end portionsand the splice member, v

7. A splice for metal package-binders em bodying a member provided witha plurality of loops each struck up initially from the 'body of themember and producing therein a pluralit of slots and producing, also, a
